aio-win32: reorganize polling loop
Preparatory bugfixes and tweaks to the loop before the next patch:
- disable dispatch optimization during aio_prepare. This fixes a bug.
- do not modify "blocking" until after the first WaitForMultipleObjects
call. This is needed in the next patch.
- change the loop to do...while. This makes it obvious that the loop
is always entered at least once. In the next patch this is important
because the first iteration undoes the ctx->notify_me increment that
happened before entering the loop.
